I have a question which is related to searching information which company has stocks assigned to which stock exhange in which country. My question is based on the comparison between Marketwatch and Bloomberg website search. I would like to know the following: I saw hundreds of cases where Marketwatch is reporting that company has stocks assigned to strictly only one stock exchange, which is usually any stock exchange in USA. However, when I do the search for identical company name, using identical words, on Bloomberg, I see in drop down menu information that same company has stocks also on at least one more stock exchange in the country which is NOT USA. Example to clarify my question, which I haven't even asked yet: Check on MarketWatch the company with name "Navistar International Corp" and memorize the country of stock exchange it is shown. Now kindly check please the same company on Bloomberg where you click on Stocks at the top menu. If you type (or paste) into Quote Search box the identical company name, you will see the company is on three different stock exchanges in three different countries. This is only one such example. I have seen hundreds of such examples and I'm assuming that there is some major misunderstanding on my side. I doubt very much that such reputable website as MarketWatch is, would provide insufficient or incorrect (repeatedly!) information, e.g. saying company has stocks on one stock exchange but in reality it does on multiple worldwide. Could anyone please tell me what's going on? Am I missing something here? Why is Bloomberg showing multiple stock exchanges but MarketWatch for IDENTICAL company from identical country ( ! ) only one stock exchange?


Great question, and to answer your question, it's important to understand that MarketWatch isn't providing as much information as Bloomberg is. It's not that MarketWatch is providing inaccurate information in any sort of way, but it's just that Bloomberg offers more widespread data to its users.

MarketWatch is a subsidiary of the Dow Jones & Company, which is then a subsidiary of News Corp.

Bloomberg News is a subsidiary of Bloomberg L.P., which is then a subsidiary of Bloomberg, Inc.

Dow Jones & Company primarily operates within the United States/North America.

Bloomberg operates all over the world/provides economic value in both domestic and international markets.

Just as any other business does, both of these companies/subsidiaries have selective markets which they target and provide value/operate in.

Because of this, MarketWatch is not necessarily going to provide incredibly expensive data to a fractional portion of the user base that makes up their revenue - just as any good company would do, they're focusing on the ~20% of their user base that will bring in ~80% of their revenue - doing it the other way around would ensure the company wouldn't be around for a long time/unprofitable (I'm using Pareto's principle as an example just to exercise my point).

To reiterate, most users of MarketWatch are typically located in the United States, so the company is going to cater towards that demographic more than it will towards an international one. Not just that, but most people/firms located within the United States don't invest/speculate/trade in international markets. This may change as globalization continues to evolve, but for the time being most United States citizens/North Americans interact with domestic markets exclusively.

Both are great resources for market data obviously, but they cater to slightly different demographics. There's obviously overlap with their user bases in the U.S./North America markets, but Bloomberg supplies their products/services to more international populations in place of MarketWatch.

I hope you found this answer helpful.
